'BERTRUM FRANKLIN SMITH, 0F NATRONA, PENNSYLVANIA.

auroivia'rio CAR-WHEEL LUBRICATOR.

To all whom it may concern:

Be itknown that I, BERTRUM FRANKLIN SMITH, a citizen of the United States of America, residing at Natrona,in the county of Allegheny and State of Pennsylvania,

have. invented certain new and useful Improvements inAutomatic Gar-Wheel Lubricators, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to an automatic car wheel lubricator, and more particularly to a device that can be advantageously used for injecting oil or a suitable lubricant into the journal boxes of cars used upon industrial railways. r

.My invention aims to provide: First, a lubricating device that can be located at the side of a track and actuated by acar thereon for injecting a quantity, of oil into an axle journal box or the hub ofa wheel. Second, a lubricating device of the above type that is automatically actuated by a car to inject lubricant into a wheel hub as a car is .moving, the construction of the dev ce being such as to permit of. movable parts thereof yielding. whereby under ordinary conditionsthe device can be safely used with a minimum amount of repair. Third, a lubricator of the above type embodying a novel pump that is supplied with oil the oil a being automatically ejected from the pump as the pump is actuated by the tread or flange of a car wheel. Fourth,a lubricating device of the above type consisting of comparatively few parts that are easy to assemble, durable, inexpensive to manufacture, and highly efiicient for the purposes mechanical construction that will be herefor which they are intended.

I attain the above and other objects by a inafter specifically described and then claimed, and reference will now be had to the drawings, wherein Figure-1 isa perspectiveview of the lubrieating device, showing the reservoir partly broken away and partly in section. Fig. 2

is a plan of the device as actuated by a car wheel. Fig. 3 is a similar view showing the device in its normal position; Fig. l is a side elevation of the device as actuated by a car wheel. Fig. 0 is a side elevation of a 7 portion of the track showingthe equipment as actuated by a car wheel. Fig. 6 is an enlarged longitudinal sectional view of a nozzle. Figs. 7 and 8 are longitudinal sectional views of the pump, and Fig. 9 is a Specification of Letters Patent.

side elevation of the track equipment in its normal position.

In describing my invention by aid of the drawings above referred to I desire to point out that I intend said views as merely illusv arrangements and constructions which are the obvious equivalent of those shown.

In the drawings 1 denotes a. base plate that is rectangular in plane and-this plate can be mounted upon a suitable foundation at the side of the track. It is preferable to use ties 2 of greater length than the ordinary ties and mount the plate upon the ends extending under a 'rail 3 of the track.

Secured to the base plate 1 are A-fraines l and5, the framed having a strap 6 supporting a pump cylinder 7. The frame 5 The T connection 8 is conable reservoir 11 adapted to contain oil or other lubricant. A conventional form of check valve 12 is located upon the pipe 9 and this check valve prevents oil from be ing forced into the reservoir 11 after having once entered the T'connecti-onS and the cylinder 7. The T connection 8 is connected by an elbow 13 to'an elbow swivel connection lat having a pipe 15 provided with a valve 16. Connected to the valve 16 is a sec tional telescopic nozzle pipe, said pipe comprising an inner section 17 and an outer section 18, said outer section telescoping the inner section, as best shown in Fig. 6. The outer section 18 is slotted, as at 19 and the inner section 17 has a transverse pin 20 that extends into said slots and limits the movement of the outer section relatively to the inner section. The outer section 18 hasa reducing head 21 and encircling said sections, between the head 21 and a stirrup 22 isa coiled compression spring 23 that holds the outer section normally extended rela tively to the inner section. The stirrup 22 encircles-the inner end of the section 17 and this stirrup will be hereinafter more fully referred to. i

The reducing head 21 has nozzle 24:

and an inwardly extending spring housing Patented Jan. 19, 1915. 7

,of the ties with the inner end of the plate supports a l connection 8 that is connected to the cylinder 7.

nectedby pipes 9 and an elbow 10 to a suit 26 and movable in said spider is a stem. 27 of a valve 28 adapted to normally close the spider. The valve 28 is retained in engagenient with the spider 26 by a coiled compression spring 29 mounted in the housing 25, and said housing has a nipple 30 extending into the inner section 17, whereby it can readily receive oil from said section;

Movable in the cylinder 7 is a piston head 31 provided with a piston rod 32 that extends out of the end of the cylinder. I The piston rod 32 has a cross head 33 and encircling said piston rod, between the end of the cylinder 7 and the cross head 33, is a coiled retractile spring 34 that has the ends thereof attached to said cross head and to theend of the cylinder. The tension of this spring is suilicient to hold the piston head 31 in a retracted position in proximity to the. end of the cylinder, whereby oilcan flow from the reservoir 11 into the cylinder and the T connection-8.

' Connected, as at 35 to the ends of the cross head 33 are parallel rods 36 having bifurcated-ends, pivotally connected, as at 37 to 1 theends ofa yoke 38. The yoke 38 is mounted upon a rock shaft 39, journaled in bearings 40, carried by the base plate 1, beneaththe pipe 15. Mounted upon the shaft 39 is, one end of lever 41, said lever extending over a slot 42 formed in the plate the outer end of said lever. 35

1 to provide clearance for a depression of The shaft 39 connects the yoke 38 and lever 41 together. The outer end of said lever is substantially hook -shaped, as at 43 and is mounted in a notclr44 provided therefor in the bottom side of anarm 45 that is fulcrumed or pivoted upon the side of the rail 3, as at 46. The arm 45 has a curved tread end 47 adapted to bedepressed by the tread 48 of a wheel 49. The end ofthe lever 41 is held in the notch 44 of the arm 45 by a strap 50 and it is through the medium of this con: nection that the tread portion 47 of said arm is held normally elevated by the tension of the spring 34, which retains the piston head 31 in a retracted position.

The plug 51 of the two-way valve 16 has a stem 52 and mounted upon said stem is a bell crank A11 arm of said crank is connected. by a coiled retractile spring 54 to the swivel elbow and the same arm has a connection 55 with the stirrup 22. The other arm of said bell crank is connected by a link 56 to the crank 57 of a rock shaft 58. The rock shaft 58 is journaled in a bearing 59, carried by an upright 60, secured to the base platel. The rock shaft 58 has a crank 61 pivotally connected, as at 62 to the crank 63 of a rock shaft 64. The rock shaft 64 is journaled in a bearing 65, carvried'by the base plate 1. Therock shaft v64 has another crank in the form of a trigger 47 is depressed and the hook-shaped end of the lever 41 18 elevated, thereby rocking the shaft 39, nioving the yoke 38, shifting the rods 36 and moving the by thepiston head 31 is-placed in a retracted position and the coiled spring 34 under tension; This position of the spring is shown in Fig. 7 and in consequence of thepiston head 31 being placed in a retracted position the cylinder 7 receives a greater charge of oil. As the crown or bell 67-of the Wheel 49 impinges the trigger 66, the shafts 64 and 58. are rocked, thereby moving the bell crank 53 and opening the valve 16. Simultaneous with the opening of the valve 16the stirrup 22 is advanced upon the nozzle pipe and the tension-of thespring 23 is sufficient to extend thenozzle pipe section 18, whereby the n'ozzle24 will be placed in a v D or the opening 70 of the crown orlbell 67 of the wheel 49. By. this time a quantity of oil has passed into the telescopic nozzle pipe, and as the stem 27 of the valve 28 impinges the end of an axle 71 or an elementof the journal box, the valve 28 is opened thereby establishing communication between the wheel and the telescopic nozzle pipe. At this instant in the operation of the device the tread portion 47 of the arm 45 is released and the lever 41, yoke 38 and the rod 36 released, whereby the spring 34, which has been placed under tension, can shift the piston head 31. fore ejectedfromthe telescopic nozzle pipe into the nipple 30, through the housing 25 andv the spider 26 and from the nozzle 24.

f course. the wheel 49 is slowly moving and in order that sufficient time-lapse for the in- A quantity of oil is thereencounters the tread cross head 33, where- 1 journal box jection, the elements 14 to 27 inclusive shift that it is the rapid action of a compressed spring being released that produces the injection of oil into a wheel or the journal boX thereof, and that the valves are so arranged as to practically simultaneously operate in controlling the injection. With the nozzle yielding in a lateral plane a portion of the injection takes place during its movement and the movable parts of the device can be timed to operate whereby the loss of oil is reduced to a minimum.
